STORAGE BATTERY.

Specification of Letters Patent.

Application filed May 12, 1915. Serial No. 27,481.

To all whom it may concern:

3e it known that I, THEODORE A. WILLARD, a citizen of the United States, and resident of Cleveland: in the county of Guyahoga and "State of Ohio, have invented a certain new and; useful Improvement in Storage Batteries;- ol which the following is a full. clear. and exact description.

This invention relates to storage batteries and to a method of sealing the jar and batte'i'y box.

()ne of the objects of this invention is to seal the jar in the battery box in such a manner that an air space is provided around the top of the cell or jar for ventilation, and at the same time the cell is held securely in the. box.

it. further object is to seal the jar in the boxv in such a manner that it the battery is ovei'tilled or overflows there will be good 'lrainag'e and still the acid cannot soak into thev wood surrounding the openings providdd tor drainage and ventilation.

"fl he above and other objects are attained by my invention, which may be briefly summarized as consisting in certain novel combinations and arrangements of parts and steps oi the method whi h will be described in the specification and set forth in the rip ,pended claims.

In the accompanying sheet or drawings Figure l is a sectional view through the battery 1m showing: the manner in which the bottom ot the cell is sealed in the box; Fig. 2 is a siuiilar'view showing both the box and jar ot t'hp cell in vertical section with the jar scalediin the box; Fig. 3 is an end view of the box.

it have shown one emlmdiment of my in \jen'tion in he drawings, in. which it) reprebicnts the battery box which is usually formed t fwood, and which is rendered acid proof painting with acid proof paint or by otherwise treating the same. This battery box receives one or more cells, usually a plurality ot the cells, ea h ol' which includes a jar It adapted to contain the battery solution and the usual positive and negative battery plates which are Sll])]')0ltt(,l. on upstand- To securely seal or hold the ing' tlaufJcs l2.

ja r or jars it in the box 10, and at the same time provide better ventilation than has hcr totore beenobtainable around the out- ;idh'ot the jar or between the upper portion ings.

of the jar and the box, 1 form in the walls of the box ventilating and drainage openings 13 which are provided at a predetermined distance from the bottom of the box. I then place in the box, before the jars are lowered in the same, a melted sealing compound 1% havingan asphaltuni or pitchy base, the box being filled to a depth such that when the jars are lowered into the box the sealing eompoundwill run out of the openings 13. The jars are then placed in the box, and by means of .a suitable weight which will be placed on the jars the latter will be forced down to the bottom of the box, shown in Fig. 2, displacing the sealing compound and causing a certain portion to flow out through the openings 13. The jars which are smaller in dimensions than the inside dimensions of the box, when lowered, are spaced from the walls of the'boX, shown in the draw- Then, when the jars rest firmly on the bottom of the box, the compound is allowed to cool and set or become hardened,

atter which the droppings are cleaned ott' the outside of the box.

In this manner the jars a re securely sealed and ield rigidly in the box, but at the same time there is a. ventilating space 15 provided around the upper portion of each jar, which admits of the circulation of air around that part of the jar which in practice becomes the hottest, cool. air entering the openings 13 and the heated air passing upward trout the ventilating spaces 15. Furthermore, it the battery is overtilled, as is often the case in practice, the battery solution will run down into the. spaces 15 to the sealing compound and out through the openings 13. By reason of the fact that the sealing compound was previously allowed to overflow or run out oi. the openings. 13, a coating ot' this compound overlies the lower part of each opening 13, as shown at 16 in Fig. with the result, that the acid cannot soak into" the wall of the opening.

Having: thus described my inventiomwhat l claim is:

1. ln a storage battery, :1 battery box, one or more battery jars contained in the box and spaced from the side walls thereof, and a sealing compound filling the space between the jar or jars and the side walls of the box for a predcteruliued distance up from the bottom of the box, there being an overflow Patented May 1, 1917.
